Journal ArticleDOI
Localization of Plasmodium falciparum histidine-rich protein 1 in the erythrocyte skeleton under knobs.
Diane Wallace Taylor,Marcela Parra,George B. Chapman,Mark E. Stearns,Joan Rener,Masamichi Aikawa,Shigehiko Uni,Stephen B. Aley,Lindsey J. Panton,Russell J. Howard +9 more
TL;DR: Immunofluorescence and immunoelectron microscopy of intact, non-fixed K+ infected erythrocytes using mAb 89 and a rabbit antiserum raised against purified PfHRP-1, failed to identify any surface exposed epitopes.
Journal ArticleDOI
ARL1 and membrane traffic in Saccharomyces cerevisiae.
Anne G. Rosenwald,Mary Ann Rhodes,Hillary Van Valkenburgh,Vikram R. Palanivel,George B. Chapman,Annette L. Boman,Chun-jiang Zhang,Richard A. Kahn +7 more
TL;DR: It is demonstrated that ARL1 encodes a regulator of membrane traffic in Saccharomyces cerevisiae, and the ts phenotype of the arl1Δssd1 strain was suppressed by YPT1, the yeast Rab1a homologue, suggesting that ARl1 and Y PT1 have partially overlapping functions.
Journal ArticleDOI
Shape and size stability of Pt nanoparticles for MeOH electro-oxidation
TL;DR: In this article, the shape and size stability of octahedral/tetrahedral Pt NPs were investigated by transmission electron microscopy (TEM) as well as cyclic voltammetry (CV).
Journal ArticleDOI
An unexpected enhancement in methanol electro-oxidation on an ensemble of Pt(111) nanofacets: a case of nanoscale single crystal ensemble electrocatalysis
TL;DR: The octahedral/tetrahedral Pt nanoparticles displayed an unexpectedly large enhancement in methanol electro-oxidation activity; about 3-fold increase in transient intrinsic activity and 10-fold rise in CO tolerance steady-state activity when compared to commercial Pt black.
Journal ArticleDOI
Ultrastructure of the distal retina of the adult zebrafish, Danio rerio.
TL;DR: Zebrafish photoreceptors have many characteristics similar to other species, further supporting the use of zebrafish as a model for the vertebrate visual system, and presumed gap junctions connecting adjacent postsynaptic processes invaginating into cone terminals are identified.
